# Learn by building a notes Agent

> One project, independently runnable chapters.

Advanced path: [Agent Design Lab](/tutorials/agent-design-lab) adds six professional design projects, currently under joint framework and live-model qualification.

Start with two synthetic notes and learn tools, state, persistence, context, multiple Agents and report publication. Learn mechanisms with an explicit fake provider, then switch to a real model through Configuration. Every chapter includes every file and can run independently.
